如何可以申請加拿大非居民

When do you become a non-resident?

When you leave Canada to settle in another country, you usually become a non-resident of Canada for income tax purposes on the latest of the following dates:

the date you leave Canada;
the date your spouse or common-law partner and dependents leave Canada;
the date you become a resident of the country to which you're immigrating.
It's important that you tell us the date you leave Canada because your residency status affects your eligibility to receive:

the GST/HST credit (goods and services tax/harmonized sales tax);
Canada Child Tax Benefit payments (and any similar provincial program payments);
Universal Child Care Benefit payments.
After you leave Canada, you're a non-resident for tax purposes provided you have severed residential ties with Canada. As a non-resident, you pay tax on income you receive from sources in Canada.

This applies in the year you leave Canada and for each year afterwards, provided you remain a non-resident for tax purposes.
The type of tax you pay and the requirement to file a Canadian tax return depend on the type of Canadian income you receive.
Generally, Canadian income received by a non-resident is subject to Part XIII tax or Part I tax. If the income you receive is:

subject to Part XIII tax, you do not file a Canadian tax return, except in two situations when you can elect to file a tax return;
subject to Part I tax, you may have to file an tax return.

This is very complicated. You should 1) either ask your wife in Canada to check with your accountant or an Immigration lawyer. Or 2) Check with the Canada Embassy in Hong Kong personally.

當然唔可以申請為 non-resident. 因為申請做 non-resident 其中一項要求係你冇 residential ties with Canada. Residential ties 即是話 1)你冇屋响加拿大, 2)你冇配偶及子女响加拿大, 3)你冇個人財產, 包括車或傢俱响加拿大, 4)你冇同加拿大社團有關係, 例如乜乜會嘅會員之類.
除咗residential ties 之外, 以下都包括, 1)冇加拿大車牌, 2)冇銀行戶口及加拿大信用咭, 3)冇响加拿大任何一個省有醫療保險咭.
如果你符合以上所有要求; 你就有資格申請 non-resident. 你唔好以為加拿大政府係傻嘅, 如果比你咁易申請咗做 non-resident; 咁你一家大細嘅醫療, 教育, 社會福利全部由其它加拿人同你揹起? 有冇咁著數呀.
